Q:The principle of material handling: Adaptive principle (flexibility principle) : adopt methods and devices that can adapt to various kinds of work and applications, unless it is a device that must be used for a particular purpose. Reduce the principle of self-importance: reduce the ratio of air to heavy load. Principle of utilization: the optimal utilization rate of planning and carrying equipment and manpower. Maintenance principle: plan all the maintenance and maintenance of all moving equipment. Obsolete principle: replace outdated methods and equipment when there are more efficient means of handling and equipment. Control (control) principle: use material handling activities to improve control of production, inventory and order processing. The principle of production ability: use the handling equipment to improve the production capacity.

Q:The function of material handling: Material handling USES all kinds of power and transport machinery to keep the material, such as count, punctually, safely, economically, and to the designated place. It is closely related to the choice of site selection and professional cooperation in the outside material handling machinery factory.

Q:The development of material handling: Domestic market competition is the basic material handling machinery, high-end market is mainly composed of multinational companies, domestic key large enterprise also had some markets in some specific fields; The participants in the mid-market market include large enterprises in China and small and medium-sized enterprises with excellent manufacturing technology and high management level. Many of the small scale, poor technology, poor management, lack of product innovation of enterprise, product quality is not high, low added value, poor economic benefit, in the industry of low-end market, competition is intense. "Twelfth five-year" period to 2020, is China's national economy sustainable development strategy implement and promote the development of circular economy, take a new road to industrialization, the basis for building a resource-conserving and environment-friendly society an important period. Attaches great importance to the society and the enterprise logistics role, vigorously develop modern logistics industry, to promote the development of and promote industry, improve the quality and efficiency of economic operation, enhance the comprehensive national strength and the enterprise competitiveness, has the very vital significance. It is an effective means of carrier for all walks of life of the national economy, including the manufacturing of material handling equipment which supplies the large amount of equipment needed for the second and third industries. The rapid and steady development of the national economy, the informationization and industrialization of the basic industries, provide the best opportunities for the manufacturing industry of materials handling equipment.

Q:The beneficial effect of material handling machinery: Material handling machinery is serving the production, its design and type selection should be subject to the needs of the production process, new material handling machinery but also often leads to the change and improvement of the manufacturing process. For example, the emergence of bucket wheel stacker reclaimer, formed the bucket wheel stacker reclaimer for heart, belt conveyor for blood vessels, the electronic computer is the nerve center of automation of large bulk material handling system, which changes the ports, mines and the layout of the power plant and so on of the bulk yard; It can simplify the structure of the factory and reduce the cost of construction.

Q:What are the requirements for the science of loading and unloading: Mechanized the moving operation. Provide functions such as production, handling and storage. The various elements of the moving material should be considered when choosing the moving equipment, including the moving and method used. Standardize the type and size of the handling and handling equipment. Adopt methods and equipment that can be adapted to all kinds of work and applications, unless you have to use a special visual device.

Q:Why should we emphasize unitization and standardization in material handling: Reducing the degree of climate impact, ensuring normal work, accelerating the flow of goods and improving efficiency. 1) logistics base module The logistics base modulus is the minimum size of the standard size of the logistics system. In basic module size was determined, the size of the various specific standards, should be based on basic module size, select the integer times to the prescribed standards for size, foundation modulus size is determined, just a standard size in multiple choice, it can be used as a standard of other size.

Q:What are the potential defects of the automated material handling system?: Stacker crane Automatic stacker crane is a machine, electrical integration of high-tech products, products mainly to the (box, bag, barrel), through a continuous mechanical action, according to certain order stack to the corresponding empty tray, to facilitate the batch product handling and transportation, so as to improve the efficiency of the production. According to the height of the entry, different stacker machine is divided into high and low stack.

Q:What is the relevant content of the flow of materials, storage and usage: What is the relevant content of the flow of materials, storage and usage? Material flow, in lean as "one-piece flow," the core idea is how to make the material in the production process is in a state of flow, however it is very difficult, a more realistic approach is to ensure that in the process of circulation between the products is the least (quantity). The real meaning of storage is what you really need at the scene. Using a process is the sequence of steps to complete a task

Q:Urgent, please go to logistics expert, the question about the warehouse: Buy a forklift truck with a solid price. You'd better consult with the company that makes the shelf and forklift

Q:What is the rational and scientific classification of logistics facilities and equipment: You can look at this book In the 21st century, the teaching materials of high vocational high vocational logistics Book this center around the logistics facilities and equipment, introduced the logistics packaging, warehouse, storage, transportation, loading and unloading handling, container unitization, port logistics, distribution processing, automatic sorting, information platform, modern logistics equipment management such as logistics facilities and equipment of theoretical knowledge and practical content. If you don't like reading, you can also check the website of the home logistics equipment.
